4 years ago You can follow this command to config vlan
# create vlan 3491 and config ip
ff_ifconfig f-stack-0.3491 create
ff_ifconfig f-stack-0.3491 inet 10.4.101.141 netmask 255.255.255.0
# clean the ip of f-stack-0, if it needed.
ff_ifconfig f-stack-0 inet <ip address> remove
# readd default router
ff_route add 0.0.0.0 <gw address>
I run helloworld --conf ./config.ini --proc-type=primary --proc-id=0 with following config,and check the interface "f-stack-0" OK. But I failed to create vlan tag on this interface with the commands "./ifconfig -p0 f.3491 create vlan 3491 vlandev f-stack-0 " and " ./ifconfig -p0 f.3491 create vlan 3491 vlandev f-stack-0 inet 10.4.101.141/24"

examples
0-3 ports 0, 1,2,3 are enabled
1-3,4,7 ports 1,2,3,4,7 are enabled

If use bonding, shoule config the bonding port id in port_list
and not config slave port id in port_list
such as, port 0 and port 1 trank to a bonding port 2,
should set

Port config section
Correspond to dpdk.port_list's index: port0, port1...

lcore list used to handle this port
the format is same as port_list
lcore_list=0
bonding slave port list used to handle this port
need to config while this port is a bonding port
the format is same as port_list

Packet capture path, this will hurt performance

orrespond to dpdk.nb_vdev's index: vdev0, vdev1...

mac : The mac address of vuser. Optional, default random, if vhost use phy NIC, it should be set to the phy NIC's mac.
cq : Optional, if queues = 1, default 0; if queues > 1 default 1.
